Hello everyone,
A friend failed to flash the firmware for his Axpert King 2 inverter control panel. I've searched, but I can't find any firmware. Could someone help me?
Thanks.

I believe so.
Actual users would have to answer this. I just patch the firmware, I can't actually run any of these.
As I've said elsewhere, the VM III and VM IV firmware numbering is very chaotic. That's most of the reason for this topic, and it only focuses on the Twin models. 60.10 from June 2024 is the latest of the 60.xx, 70.00, and 71.03 firmwares.

I would normally offer suggestions on firmware versions, but the VM III series is so chaotic that I have no idea what's going on. I might be able to research this topic, but it will be very time consuming, and other projects are far more urgent at present.
I don't even have a single 71.xx firmware for a VM III, other than 71.03 itself. It's from March 2024.

Each brand name of voltronic inverters has a different firmware version with slightly different features. I recommend going through this post so you understand the concept
Collection of DSP Axpert Firmware for VM III TWIN and VM IV TWIN
If your inverters are not clowns, you can use any available version for the specific models, and please note that the latest firmware for Axpert VM III 4k,6K Twin which was released for TribleA brand is 60.10.

I have been waiting for a similar response to this topic for a week, and unfortunately, the response was in an old version. If you find the latest version, I hope to publish it. Thank you very much.

Hello All,
I have got recently Axpert VMIII 4K twin. It has the main CPU firmware version is 00071.03, and the secondary CPU firmware version is 00057.16
Do I have the latest firmware for this inverter?
Thanks

I will be trying both firmwares, and I will writing notes about every update, Thank you sir

It seems that you would benefit from 56.11 then. I don't know where I found 56.11's hex file; it didn't seem to come with a reflash tool. [ Edit: It seems it came from this post. ] So I've added a reflash I took from 56.97 and made a zip file with what I hope is all the files you need.
If you use it, please let me know how it goes. The hex file is dated 9/Feb/2023. I have not explored this firmware in detail, but it certainly seems legitimate. Use at your own risk.
This is factory firmware version 56.11 for the Axpert VM III and VM II, 4kW and 6kW, Twin outputs. Do not use with any other model.

Please post in English on this forum.
The latest I know of in the 56.xx series is 56.11, available here. [ Edit: But see 3 posts down. ]

VM TWIN_Ver60.95.7z
Does this update work on the Axpert VM III TWIN and Axpert VM IV TWIN TWIN?
Is it only for 4 kW?
Or does it also work on 4.2 kW, 6 kW, and 6.2 kW power levels?
Please share for the benefit of all.

أم أنه يعمل أيضًا على مستويات طاقة 4.2 و6 و6.2 كيلوواط؟
ارجو المشاركة للفائدة

مرحبًا
هل يمكني العثور على افضل تحديث البرامج الثابتة لجهاز Axpert VM III TWIN 4000W Inverter Off-Grid Inverter شاشة متحركة ؟

Why are there two files?

Of course not, I hope so, I am an IT engineer and I have some interest in my inverter 
 
My inverter name is triple A vm iii 4kw 

I'm attaching two charts to this message.
Both show the start of the solar system in the morning.
Picture 1 ist with the older modified firmware 160.06 from @Coulomb
Picture 2 shows the same situation with the newer firmware 60.95
Before 8:00 the system is in charge mode (charging only), then the 230V output switches on.
In the first case, the MPPT restarts at 8:00, where the output is switched on, and finds a good working point
In the second case, the MPP tracking starts on its own.
 
 

These would be alternatives. VM III and VM IV firmwares are a big mess. It seems to be possible to intermix VM III and VM IV firmwares, though I'm suspicious about that.
There are also 56.xx, 60.xx, and 70.xx firmwares, just for the Twin models.
The latest in the 56.xx series is 56.72, available here.
The latest in the 60.xx series is actually 60.10, which may have fixed the "stuck at 60V" issue, according to this post.

Hi all! A situation has arisen, the inverter has been registered, but the credentials have been forgotten. When registering, it says that such a device is already registered. How to delete a Watchpower account and create a new Watchpower registration? Inverter Expert MAX 8000
